Call the coordinates of point P (0,b).

Find the x intercept of a line with slope 3 passing through P(0,b):






Find the x intercept of a line with slope -4 passing through P(0,b):






Use the fact that the two x-intercepts are 14 units apart to determine b.






ANSWER: The distance of P from the origin is b = 24.
